Active carbon absorbent containing rare earth element

Abstract

The invention discloses an active carbon adsorbent containing rare earth element. The active carbon adsorbent is characterized in that the active carbon adsorbent is prepared from the following raw materials in parts by weight: 100 to 150 parts of sludge, 13 to 17 parts of maize straws, 15 to 24 parts of peanut shells, 10 to 15 parts of manganese ore powder, 30 to 50 parts of zinc chloride, 13 to 16 parts of magnesium silicate, 5 to 8 parts of silicon dioxide, 3 to 5 parts of polyving akohol, 3 to 5 parts of polyacrylamide, 2 to 3 parts of lanthanum nitrate, 3 to 5 parts of polyester fiber, 2 to 3 parts of yttrium oxide, 3 to 5 parts of chlorine dioxide and a proper amount of distilled water. The added lanthanum nitrate, polyester fiber and yttrium oxide reinforce the adsorption capacity and the corrosion resistance of the sludge active carbon; the added chlorine dioxide is good in sterilization and antiseptic properties; the active carbon adsorbent is wide in raw materials sources, low in cost, simple in preparation process, high in adsorption capacity and worth being popularized.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to an activated carbon adsorbent containing rare earth elements and a preparation method thereof. Background technique [0002] With the acceleration of urbanization, the increase of urban population and the strengthening of environmental protection awareness, the discharge of urban industrial wastewater and domestic sewage is increasing, the rate of urban sewage treatment is also increasing year by year, and the sludge generation rate of sewage plants is also increasing sharply. The sludge of the sewage treatment plant has a high water content, a large amount of organic matter, toxic and harmful substances, and semi-dry solid waste with complex rheology. It has a large capacity, is easily corrupted, unstable, and has a bad smell. cause serious environmental pollution. Activated carbon is a porous adsorption material with rich pore structure, high specific surface area and strong adso...

Problems solved by technology

But ordinary activated carbon adsorbents and rare earth adsorbents have the disadvantages of being easily saturated, not easy to separate, easy to fall powder and scattered, not long in use, not easy to separate, and low in adsorption efficiency.
